Coherent structures of a hydrothermal buoyant plume in the near-field obtained through LES at ultra-high resolution.
<p>Three-dimensional coherent structures identified by iso-surfaces of lambda2 = -1 (a) and lambda2 = -10^(-2) (b) using the method by Jeong and Hussain (1995) for a buoyant forced plume (Gamma0 = 1.14, where Gamma is the flux balance parameter defined by B. Morton and Middleton, 1973). The colormap represents the absolute temperature anomaly. The time interval in the video corresponds directly to the simulation time of the plume.</p> <p>This is an output of a Large Eddy Simulation (LES) performed using the <a href="http://basilisk.fr/">Basilsk</a> code, an adaptive mesh refinement (AMR) code featuring a second-order accurate finite-volume solver for the Navier–Stokes equations. These equations are solved in their three-dimensional Boussinesq form for an incompressible fluid. The plume modeled here represents a typical hydrothermal vent, with source conditions set to 300 °C for temperature, 0.7 m/s for velocity, and a vent radius of 2.8 cm.</p> <div> <div> <div>Source :</div> <div>Jeong J, Hussain F.

Data from: The application of optical coherence tomography to image subsurface tissue structure of Antarctic krill Euphausia superba
Many small open ocean animals, such as Antarctic krill, are an important part of marine ecosystems. To discover what will happen to animals such as krill in a changing ocean, experiments are run in aquaria where conditions can be controlled to simulate water characteristics predicted to occur in the future. The response of individual animals to changing water conditions can be hard to observe, and with current observation techniques it is very difficult to follow the progress of an individual animal through its life. Optical coherence tomography (OCT) is an optical imaging technique that allows images at high resolution to be obtained from depths up to a few millimeters inside biological specimens. It is compatible with in vivo imaging and can be used repeatedly on the same specimens. In this work, we show how OCT may be applied to post mortem krill samples and how important physiological data such as shell thickness and estimates of organ volume can be obtained. Using OCT we find an average value for the thickness of krill exoskeleton to be (30±4) µm along a 1 cm length of the animal body. We also show that the technique may be used to provide detailed imagery of the internal structure of a pleopod joint and provide an estimate for the heart volume of (0.73±0.03) mm3.
Data from: The Chlamydiales pangenome revisited: structural stability and functional coherence
The entire publicly available set of 37 genome sequences from the bacterial order Chlamydiales has been subjected to comparative analysis in order to reveal the salient features of this pangenome and its evolutionary history. Over 2,000 protein families are detected across multiple species, with a distribution consistent to other studied pangenomes. Of these, there are 180 protein families with multiple members, 312 families with exactly 37 members corresponding to core genes, 428 families with peripheral genes with varying taxonomic distribution and finally 1,125 smaller families. The fact that, even for smaller genomes of Chlamydiales, core genes represent over a quarter of the average protein complement, signifies a certain degree of structural stability, given the wide range of phylogenetic relationships within the group. In addition, the propagation of a corpus of manually curated annotations within the discovered core families reveals key functional properties, reflecting a coherent repertoire of cellular capabilities for Chlamydiales. We further investigate over 2,000 genes without homologs in the pangenome and discover two new protein sequence domains. Our results, supported by the genome-based phylogeny for this group, are fully consistent with previous analyses and current knowledge, and point to future research directions towards a better understanding of the structural and functional properties of Chlamydiales.

AfriSAR: Canopy Structure Derived from PolInSAR and Coherence TomoSAR NISAR tools
This dataset contains forest vertical structure and associated uncertainty products derived by applying multi-baseline Polarimetric Interferometric Synthetic Aperture Radar (PolInSAR) and Polarimetric Coherence Tomographic SAR (PCT or PC-TomoSAR) techniques. The data were collected from multiple repeat-pass flights over Gabonese forests using the Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR) instrument in February-March 2016. In addition, supplementary data products based on various intermediate parameters of the UAVSAR data are provided and include radar backscatter, coherence, and viewing and terrain geometry. These data were collected by NASA as part of the joint NASA/ESA AfriSAR campaign.
